What are assets?
An asset is any economic resource you own or control. They can be liquid (checking accounts, savings deposits, index funds) or illiquid (real estate, private business equity, vehicles), and each type plays a different role in your personal balance sheet.
What matters for your net worth is not what you paid originally, but what your assets are worth today on the open market. A car bought for €30,000 five years ago is probably worth considerably less now, and counting it at its purchase price would distort your calculation.
- Liquid assets: cash, checking accounts, money market funds, index funds, stocks, ETFs.
- Illiquid assets: real estate, private company shares, vehicles, valuables.
- Productive assets: generate a return by themselves (investments, collected rent).
- Non-productive assets: don't generate cash flow (primary home, personal vehicle).
What are liabilities?
A liability is any financial debt or obligation that reduces your net worth. The most common liabilities are mortgages, personal loans, consumer credit, and outstanding credit card balances.
Not all debt is created equal. A mortgage on a property that appreciates over time is very different from 20% interest consumer credit card debt. Distinguishing debt with a clear purpose (leveraged debt on an asset that can grow) from purely destructive debt (consumer debt with no counterpart) is one of the most important judgement calls in personal finance.
Practical example: classifying a real balance sheet
Example. Picture the balance sheet of someone with €15,000 in checking accounts and deposits, €12,000 in an index fund, a car valued at €8,000, and a home appraised at €220,000. On the liability side, they have an outstanding mortgage of €160,000 and a car loan of €4,000.
Their assets total €255,000 (15,000 + 12,000 + 8,000 + 220,000). Their liabilities total €164,000 (160,000 + 4,000). Their net worth, the difference between the two, is €91,000: that's the figure that actually matters, not the gross value of any single asset.
How to classify your balance sheet correctly
Perform a two-step inventory. First, list all your assets at their current market value, not their original purchase price. Then, list all outstanding debt balances, not the monthly payment you make. The difference between the two lists is your net worth.
The most common mistake is counting a property's gross market value without subtracting the associated mortgage. A €300,000 home with a €200,000 mortgage adds only €100,000 to net worth, not €300,000.
Assets that commonly cause confusion
A few items generate recurring confusion when classifying them. Pension plans are assets, but with important nuances: their liquidity is restricted and, upon withdrawal, they're taxed as earned income rather than as capital gains (see our full breakdown in pension withdrawal taxation).
Personal valuables (jewelry, art, collections) are technically assets, but it's worth including them only if they represent a material, verifiable amount: listing dozens of small items with little resale value only adds noise to your balance sheet without improving its accuracy.
From inventory to a system
Once you've classified your assets and liabilities properly, the natural next step is tracking your net worth regularly and connecting it to your cash flow, so you understand not just what you have today, but where your balance sheet is heading month after month.

Frequently Asked Questions
Yes, but only its net equity (market value minus remaining mortgage). Be conservative with valuations since it is typically not an asset you plan to liquidate in the short term.
Yes. They are short-term liabilities, usually with a high cost (around 20% annually). Paying them off first usually offers the best immediate financial return, ahead of almost any investment.
Yes, though with nuances: their liquidity is restricted until retirement (with some exceptions) and, upon withdrawal, they're taxed as earned income. Their true net value depends on your marginal tax rate at the time of withdrawal.
For real estate, vehicles, or businesses without a public quote, use a prudent reference (an estimated market value, not an aspirational one) and revise it infrequently, rather than updating it every time an online estimate changes.
Only if their value is material and verifiable. Including many small items with little resale value adds noise to your balance sheet without adding real precision to your net worth.
